My car recently turned 100k miles in February. She isn't really showing signs of the Vanos failing,but with the recent performance mods I have done I think I should do them now before things start to go bad.I'm wondering if I should spend the money with Dr.Vanos and just get the unit with the new seals already installed, or get the Beisen systems kit? Also, if anybody has done their own seals and feels like giving me a hand or some pointers,I'm goin to do it either this weekend or next.. ... Thanks ...
